You didn't answer this question.

You answered

More than 2.9 million U.S. women with a history of the disease are alive today, mainly because of early detection. The five-year survival rate is close to 100 percent if the cancer is detected before it spreads.

A. TrueB. False

2. Older women are more likely to develop breast cancer.

You didn't answer this question.

You answered

The correct answer is

Breast cancer is more common in women over 55 years old. Women of any age can develop this disease, however.

A. TrueB. False

3. More than half of breast lumps are cancerous.

You didn't answer this question.

You answered

The correct answer is

About 80 percent of breast lumps are not cancer.

A. TrueB. False

4. It's OK to use deodorant on the day you have a mammogram.

You didn't answer this question.

You answered

The correct answer is

Using deodorant can make the X-ray hard to read. You also should not use any lotions or powders under your arms or on your breasts that day.

A. TrueB. False

5. Women who drink more than one alcoholic beverage a day increase their risk for breast cancer.

You didn't answer this question.

You answered

The correct answer is

The American Cancer Society (ACS) says the use of alcohol slightly increases the risk of getting breast cancer. One drink a day may cause a small increased risk; two to five drinks a day increases the risk to about 1½ times the risk of women who drink no alcohol.

A. TrueB. False

6. The best time to examine your breasts is two weeks after your period starts.

You didn't answer this question.

You answered

The correct answer is

The U.S. Preventive Services Task Force (USPSTF) does not recommend breast self-exams (BSEs) because evidence suggests BSEs do not lower risk for death from breast cancer. The ACS says BSEs are an option for women 20 and older as a means of familiarizing themselves with their breasts so they can notice changes more easily. Talking with your health care provider about the benefits and limitations can help you decide if you should start performing BSEs. If you choose to do a BSE, the best time is one week after your period starts. Check your breasts on the first day of each month if you have gone through menopause.

A. TrueB. False

7. Women who have their first child before age 30 and breastfeed for longer than six months are less likely to develop breast cancer.

You didn't answer this question.

You answered

The correct answer is

The risk for breast cancer increases somewhat for women who have children later in life or who have never had children.

A. TrueB. False

8. Smoking may increase your risk for breast cancer.

You didn't answer this question.

You answered

The correct answer is

The ACS says although no direct link between smoking and breast cancer has been discovered, some studies suggest it might increase breast cancer risk. This is particularly true for women who start smoking as teens.

A. TrueB. False

9. Breast cancer can be treated by surgery, radiation, and chemotherapy.

You didn't answer this question.

You answered

The correct answer is

Often, more than one type of treatment is needed.

A. TrueB. False

10. Starting at age 30, women should have a mammogram every one or two years.

You didn't answer this question.

You answered

The correct answer is

Mammography is an important tool for detecting breast cancer early, when it’s easiest to treat. But the benefits and limitations of mammography vary based on factors like age and personal risk. Experts have different recommendations for mammography. Currently, the USPSTF recommends screening every two years for women ages 50 to 74. The ACS recommends yearly screening for all women ages 40 and older. Women should talk with their health care provider about their personal risk factors before making a decision about when to start getting mammograms or how often they should get them.

A. TrueB. False

11. A woman's chances of developing breast cancer are higher if her mother, a sister, or daughter had it.

You didn't answer this question.

You answered

The correct answer is

The ACS says women who have a mother, sister, or daughter with breast cancer have about double the risk. Women whose close blood relatives from either the mother’s or father’s side of the family had breast cancer also have an increased risk for the disease.

A. TrueB. False

12. It's safe for women to use hormone therapy for a prolonged time during menopause.

You didn't answer this question.

You answered

The correct answer is

In 2005, the ACS said that long-term use of hormone therapy (HT) may slightly increase the risk for breast cancer. HT may also increase the risk for heart disease, blood clots, and strokes. Breast cancer in women who use HT for a prolonged time is often found at a more advanced stage, the ACS said. This may be because HT makes it more difficult to find breast cancer on a mammogram. The risk for breast cancer drops back to normal five years after a woman stops HT. Taking estrogen alone does not seem to increase the risk for breast cancer as much, if at all, according to the ACS. If HT is needed, it's best to use it at the lowest dose needed to control symptoms and for as short a time as possible.

A. TrueB. False

13. Regular exercise can reduce your risk for breast cancer.

You didn't answer this question.

You answered

The correct answer is

Studies show that exercise reduces the risk, but how much exercise is not known. One study found that 75 minutes to 2-1/2 hours per week of brisk walking reduced the risk by 18 percent.

A. TrueB. False

14. Breast cancer is the leading cause of death in women ages 35 to 54.
